As per my understanding, 2 same seed nodes per dc is the way to go..
If u r not creating two isolated set of nodes in ur cluster, there may be nodes referring each other in a way that everyone is able to know everyone else..

I think you could end up with partitioning where a you have two cliques of nodes that gossip to each other but not to nodes outside the clique On Jul 25, 2015 3:29 PM, "rock zhang" <r...@alohar.com> wrote: Hi All, I have 6 node, most of them are using node1 as seed, but I just find out 2 nodes are using node3 as seed, but everything looks fine. Does that mean seed node does not have to be same on all nodes ? Thanks Rock
